The correct answer is: Heartburn often results when the gastroesophageal sphincter fails to close properly.

The gastroesophageal sphincter is a muscle located at the bottom of the esophagus that has to be relaxed in order to allow food to flow down into the stomach. After it contracts (tightens), the food and the stomach acid can’t flow back up into the esophagus.

When the gastroesophageal sphincter fails to close properly acid reflux occurs and causes the heartburn.

Kobotan [32]

Some students feel distressed only in test situations. They might be said to suffer from Acute Stress.

Answer: Option B

<u>Explanation:</u>

Stress is your body's reaction to specific circumstances. It's abstract, so something that is distressing for you may not be unpleasant for another person. There is a wide range of sorts of stress and not every one of them is terrible. Stress can enable you to act rapidly in a crisis or help you comply with a time constraint.

Acute stress is the most widely recognized sort of pressure. It's your body's prompt response to another test, occasion, or request, and it triggers your battle or flight reaction.
